Taco Factorial Calculation

Compute the factorial of a given positive integer n. The factorial, denoted as $$n!$$, is defined as:

$$n! = 1 \times 2 \times \cdots \times n$$

Your task is to read an integer from the standard input, compute its factorial, and output the result to the standard output.

Note: For this problem, you can assume that the input will be such that the factorial will fit in a 64-bit integer.

inputFormat

The input consists of a single integer n provided via standard input.

Example: 5

outputFormat

The output should be the factorial of n printed to standard output.

Example: For the input 5, output should be 120.
